A 24-year Danish study of over 1.2 million children found no link between aluminum-adjuvanted vaccines and conditions like autism or autoimmune diseases, supporting vaccine safety despite ongoing concerns.
A large study in Denmark suggests that hormone therapy used to manage menopausal symptoms may be associated with an increased risk of developing Alzheimer's disease and other types of dementia. However, experts caution that the study was unable to establish causation and may be confounded by the symptoms of menopause, which themselves are linked to dementia. Other studies have shown contradictory evidence, with some suggesting a reduced risk of dementia with hormone therapy. The study only examined a specific formulation of hormones, and experts emphasize that different hormone formulations can have different outcomes.
A large Danish study published in The BMJ suggests that menopausal hormone therapy is associated with an increased rate of dementia and Alzheimer's disease. The study found that both long-term and short-term users of hormone therapy, including those who started treatment around the age of menopause, had a higher risk of developing dementia. The researchers call for further studies to determine if there is a causal effect between hormone therapy use and dementia risk. However, an editorial accompanying the study cautions against inferring a causal relationship and emphasizes the need for randomized clinical trials to provide stronger evidence.
A Danish study involving over six million participants found that cannabis use disorder significantly increases the risk of developing depression and bipolar disorder. Despite the link, researchers stress that the study doesn’t conclusively prove that cannabis use causes these mental health conditions, advising caution in use and consideration in legalization debates. The study is the largest of its kind in the world and recommends caution when it comes to using cannabis.
